The efficacy of reconstructive therapy in the surgical management of peri-implantitis: A 3-year follow-up of a randomized clinical trial.

At 36 months, treatment results obtained at 1 year were sustained following both GBR and OFD in patients attending supportive peri-implant therapy. GBR resulted in more RDF and higher composite treatment success rate than OFD (ClinicalTrials.gov Identifier [NCT02375750]).
